A blowtorch is one of the most indispensable things in everyday life, because with its help you can not only warm up frozen elements of locks or vehicles (snowmobile owners are especially familiar with its need), but also perform no less important work like tarring poultry, pig carcasses and so on and so forth. Many craftsmen have learned not only to effectively repair it, replacing worn-out parts, but also to even make a blowtorch with their own hands from available materials. But, first things first, the easiest way to make this multifunctional device at home is to make an open-flame lamp from a copper pipe with an insert. Samu copper pipe made curved at a right angle, using a special connecting corner for this purpose. A second piece of pipe is attached to this corner, but only of a shorter length.

Among other things, you will need such auxiliary fastening devices as ball valves with a rotating mechanism, firmly mounted on a copper or metal pipe section, a nut, a tip and a coupling device. Connection work is carried out using washers, modification no less than M6. The most difficult stage in performing a blowtorch at home is the manufacture and fixation of the burner. To ensure maximum convenience When adjusting the tip, it is best to weld the nut to the inner walls of the copper, which, as is known, have a very small thickness. Moreover, this approach makes it possible to significantly simplify not only the procedure for fixing the tip, but also its dismantling and replacement. After this, through holes are made along the entire diameter of the part, the main purpose of which is rigid coupling.

In order to maintain the most accurate level of the aligned connection parts during subsequent soldering, you will need to temporarily fix an auxiliary bolt, which is removed immediately after completion of the work as it is completely unnecessary. To attach the tip, the height of which ranges from eight to ten millimeters, you will need a special recess in the workpiece, the size of which will be about 4.5 millimeters. Also, don’t forget about this the most important stage, which occurs at the final stage of the work process, like wrapping those areas with a special fine mesh ball valve, which are adjacent to each other. Ultimately, if you follow the instructions correctly, it should lie exactly under the washer with the M6 ​​modification. Such a simple device will help to stop the gas supply in time, which is undoubtedly very convenient.

At the same time, one cannot say that we are talking about the most powerful tool, but to cope with the above simple tasks it can, and quite well. If desired, you can make a more complex device that can not only heat or burn surfaces, but also melt them. As an example, we can consider a gas burner made in the form of a spray gun, a more advanced prototype of which is widely used by jewelry craftsmen. To do this, you will need a durable container made of stable materials such as plexiglass or metal, the average volume of which will be about one glass (200-250 milliliters). The body of such a mini-burner itself is best made of brass, and the shut-off valve is not welded or screwed onto the thread, but rubbed in using a special paste.

As many have probably already guessed, we are talking about GOI paste. At the same time, before putting the spray burner into operation, you should definitely check the quality of the grinding and this is very simple to do. To do this, the brass body, together with the tap mounted on the GOI paste, is lowered into the water and the hole is plugged with a finger. After this, air is supplied to the workpiece by pumping the connected bulb and the presence of oxygen bubbles emanating from the joints is observed. If they are completely absent, it is concluded that the connection was made efficiently. In order to make it absolutely safe to attach the body to the vessel itself, a gasket must be used in this place to ensure complete tightness. The burner itself is also machined from brass, and in the absence of special auxiliary devices, its manufacture can be ordered from a qualified specialist.

The blowtorch is heating device, with the help of which one obtains high temperature when carrying out flammable combustion of some initial flammable substances. Such substances used during operation of the device are:

• petrol;
• alcohol;
• kerosene and some others.

A blowtorch will help you cope with a large number of tasks: heat a nut that cannot be unscrewed, heat up tar, etc.

The combustion products obtained during the operation of the device form an elongated torch, and the temperature of the torch is very high.

The most common type is the gasoline blowtorch. In addition to this modification, blowtorches have become widespread, in which the flame source is natural gas. This type of blowtorch differs from gasoline ones not only in the type of fuel burned during their operation, but also in design. The volume of tanks used for fuel in blowtorches can vary depending on the model of the device from 0.1 to 2 liters. The thermal power of these devices can vary in the range from 0.5 to 3 kW depending on the fuel supply. The lamp power is regulated using a special tap that opens the supply of the combustible substance.

Design of a gasoline blowtorch

In a gasoline device blowtorch There are two main structural parts - a fuel storage tank and a burner.

An ejector is a device in which kinetic energy is transferred from one medium moving at a higher speed to another.

The burner is called an ejector. The ejector has a design that promotes the flow of air and decaying combustion products during the combustion process. The operating principle of this device is based on creating thrust due to fuel combustion.

A supply of fuel is poured into the tank, after which it is closed with a tight lid with a seal. The lid with a seal prevents fuel leakage during storage of the device, as well as during its operation. Gasoline storage tank is supplied pumping device allowing air to be pumped into the tank to create excess pressure in it. Excess pressure contributes to the transportation of gasoline from the tank to the burner during operation of the device.

A typical device contains the following structural elements:

• fuel tank;
• handle for holding the device during operation;
• hermetically sealed fuel filler neck;
• pump with valve - to create excess pressure in the tank;
• siphon tube providing fuel supply to the evaporator;
• a needle valve used to regulate the fuel supply;
• evaporator;
• nozzle;
• ejector;
• nozzle cleaning device.

The fuel filled into the device tank is consumables. The smokiness of the flame and the clogging of the nozzle depend on the quality of the fuel used; in addition, the degree of explosion hazard that occurs during the use of the device depends on the quality of the fuel. For normal operation Gasoline devices require the use of special gasoline or gasoline with an octane number of at least 80. If low-quality fuel is used, the device may require repairs.

Technical characteristics of a gasoline-powered blowtorch

The design, configuration and weight of the blowtorch depends on the model.

A blow torch is useful in household tool. Tool models produced in Russia have different technical parameters and fuel consumption. There are several parameters that characterize these devices. In order to choose correctly suitable model tool, you need to familiarize yourself with the technical parameters of the products. The common parameters for all devices are the following:

• fuel tank capacity;
• established indicator of maximum filling of the fuel tank;
• maximum permissible pressure during operation;
• fuel consumption;
• tank diameter;
• weight of the device without fuel;
• availability of manufacturer's warranties;
• device service life.

The technical characteristics of the device determine the popularity of blowtorch models. The most popular devices are those with a tank volume of about 2 liters. These models have an established maximum filling rate of around 1.5-1.8 liters, the maximum permissible pressure during operation is 0.3 MPa. The fuel consumption of most of the most common models is 1.2 liters per hour. The mass of such blowtorches in dry, unfilled form is about 2 kilograms. Most manufacturers of these products provide a one-year warranty on their products. The service life of most manufactured products Russian manufacturers is 5 years.

The principle of operation of a blowtorch

The blowtorch can run on kerosene and gasoline.

After refueling the device, air is pumped into the tank using a pump, which creates increased pressure inside the fuel cylinder. Overpressure air ensures the displacement of fuel into the burner, where it burns and forms a flame. To ignite the burner and ensure stable operation, it must be preheated to a certain level. To carry out heating, a fuel cup is used, which is mounted under the burner. The capacity of one cup is usually enough to heat the burner to the desired temperature.

When a certain burner heating temperature is reached, the fuel supplied from the reservoir to the burner evaporates in the evaporator. Gaseous fuel enters the combustion area and forms a flame through a special nozzle. During the combustion of evaporated fuel, oxygen is sucked into the combustion area and the process is maintained.

During the process of heating the burner, air is not pumped into the tank for safety reasons, and the shut-off valve must be closed at this moment. The shut-off valve opens only after the burner and evaporator have warmed up. After opening the shut-off valve, the flame strength is adjusted. After finishing work with the device, turn it off by screwing in the shut-off valve.

Product Application Areas

About ten years ago, this device was used in every case where it was necessary to heat surfaces or metal. This product was very often used in production, since most often there was no replacement for it. A blowtorch is used in cases where heating is required in the absence of alternative sources of thermal energy or in the absence of the possibility of using modern technology.

The blowtorch is used for: heating the soldering iron tip, welding metal parts up to 1000 degrees, melting metal up to 900 degrees, for removing varnish coating, when heating frozen pipes.

Most often this device is used in the following situations:

• if it is not possible to use an electric soldering iron during work, the device allows you to perfectly heat up both the solder and the soldering iron tip;
• if it is necessary to weld metal workpieces made of metals whose melting point is below 1000 degrees;
• If necessary, carry out the melting of metal having a melting point below 900 degrees;
• the tool is used when it becomes necessary to remove the varnish coating on the surface of objects made of metal;
• when heating and thawing frozen water in water supply and sewerage pipes;
• if it is necessary to carry out the operation of heating a car engine.

In some cases, a blowtorch is used to loosen bolts and other connections when disassembling them, if these connections have become rusty. In addition, this device is used in agriculture when slaughtering livestock to resin animal skins.

Blowtorch Operating Instructions

Before using the device, you must read the instructions on how to use a blowtorch. You can use this device only after you have read the instructions.

The use of the device is only permissible outdoors. If there is an urgent need to use the device in a closed space, it can be used for a short time, followed by high-quality ventilation.

When using the device, you must strictly follow the operating instructions.

Failure to follow safety precautions when working with a blowtorch can lead to its explosion and other dire consequences.

• Before starting work, the device is refueled if necessary. The tank should be filled to three-quarters of its volume. An empty volume is required to create pressure during operation.
• Excessive pressure must be created in the tank using a pressure pump built into the device. To create pressure, you will need to perform up to 10 gentle pumping motions.
• After obtaining increased pressure, you need to pour fuel into the burner bath. It is best to use alcohol for this purpose, since this fuel does not produce a large amount of soot. The fuel poured into the bath is ignited to ensure initial heating of the burner evaporator. During the combustion of fuel in the bath, it is necessary to protect the device from drafts.
• After combustion of the fuel poured into the bath stops, the needle valve is opened. The fuel coming from the evaporator must be gaseous - if droplets are detected in the fuel flow, the procedure for heating the burner evaporator should be repeated.
• After receiving a jet of gaseous fuel, it is ignited. If necessary, the volume of incoming fuel can be adjusted using a needle valve. To speed up the process of completely warming up the burner, you can place the lamp near metal sheet, and the distance from the sheet to the burner nozzle should be 2-3 cm.
• When carrying out work, monitor the state of the torch - you can increase or decrease it using a needle shut-off valve.
• If there is instability in the operation of the burner or combustion damping occurs, then it is necessary to clean the nozzle with a needle specially designed for this purpose.
• After completion of work, the device torch is extinguished. Extinguishing the torch of the device is carried out by screwing the valve and lowering the needle. After the lamp has cooled, the air is bled from the tank.

When working with the tool, precautions should be taken.

Precautions required when working with a blowtorch

When working with a lamp, strict adherence to safety regulations is required. The fact is that violations of the rules for working with this device can provoke an explosion of the device. A blowtorch is a fire hazard. The fuel storage tank is located very close to the open flame of the torch.

When operating the device, the following rules must be observed:

• It is prohibited to operate the tool if fuel leaks or fuel vapors are detected in the structure;
• It is prohibited to use fuel during operation of a blowtorch that does not comply with the manufacturer’s recommendations;
• It is prohibited to operate the device for a long time, since the close location of the burner provokes heating of the fuel cylinder above 50 degrees Celsius;
• It is prohibited to use the device if a malfunction of the safety valve is detected;
• Do not fill the tank with fuel while the burner is burning;
• It is not recommended to use the device in enclosed spaces.

In addition, it should be said that failure to comply with almost any of the safety rules when working with a blowtorch can provoke an explosion and unpleasant consequences.

Following simple safety rules allows you to achieve maximum efficient work devices during operation.

Blowtorch is a portable burner with a directed flame used to heat parts. This adaptation is widely used in everyday life, and therefore there is a high probability that the lamp may break. This adaptation can be repaired even at home.

You will need

• – screwdriver;
• – needle;
• – wire;
• – oil for lubrication;
• – pliers.

Instructions

1. Every tool used in everyday life has its own “Achilles heel”. The most common malfunctions of a blowtorch include failure of the pump, which builds up pressure in the tank with “fuel,” and clogging of the nozzle. It is somewhat less common to encounter a malfunction shut-off valves.

2. Observe the soldering area lamp and determine the problem. You will probably find out the reason that led to this breakdown.

3. If, after opening the valve, “fuel” oozes or bubbles, but is not supplied properly, then the problem is rooted in the nozzle. Clean the calibrated hole with a needle. If there is no result, then you will have to clean this component of the portable burner in a slightly different way.

4. Unscrew the jet and try to clean it again. After this, insert a thin wire into the fuel pipe, open the valve and flush this channel with gasoline. After completing the procedure, install the nozzle in place and secure it.

5. A malfunction of the blowtorch may manifest itself in the fact that hissing or other extraneous noise is heard during operation of the burner. The problem in this case is rooted in a malfunction of the inflating device.

6. In order to eliminate a malfunction related to the operation of the pumping device, unscrew the plug and remove the pump out. Remove the spool, the one located on the pump valve, clean this element of the burner structure from blockages and replace its spring. Lubricate the seals on the rod motor oil.

7. If a flame begins to blaze from under the rod while the blowtorch is operating, extinguish the fire, and later remove the valve handle and plug and then change the gland packing of the intake needle.

On the eve of winter cold, a caring owner is obliged to check the functionality of the blowtorch. In order to avoid incidents related to the fact that precisely at the moment when something urgently needs to be heated, it turns out that it is impossible to do this due to a non-working device.

You will need

• – screwdriver,
• - pliers.

Instructions

1. Particularly frequent failures in the operation of a blowtorch occur due to a clogged nozzle or a malfunction of the pump that pressurizes the gas tank. Failure of shut-off valves is very rare.

2. Let's start in order.

3. First. If, while the pump is pumping air pressure into the fuel tank, a hissing sound is heard from underneath it or gasoline penetrates inside and is squeezed out by the rod moving upward, then the pumping device is repaired. For this purpose, the plug is unscrewed, the pump is removed out and disassembled. A valve is installed at the air outlet from the pump, consisting of a spring and a ball adjacent to a ground seat. The spool is disassembled, cleaned of debris and its spring is replaced (if it is damaged by corrosion or bent). When assembling the pump, the condition of the cuff on the rod is checked; if satisfactory, it is lubricated with engine oil. Otherwise, it is replaced with a new one, after which the pump is assembled and installed in its original location.

4. Second. The air pressure in the tank is increased, but after the valve is opened, gasoline is not squeezed out of the nozzle in a stream, but bubbles and flows down in drops. Try using the supplied needle to clean the calibrated hole. If this does not work, then the jet is unscrewed and cleaned. After this, you need to slide a thin iron wire into the fuel pipe, then open the valve and flush the channel with gasoline, and screw the nozzle into place.

5. Third. After the lamp flares up, gasoline is squeezed out from under the valve stem and ignites. To eliminate dangerous manifestations, the flame of the device is extinguished, the residual air pressure is released from the tank, the valve handle is removed from the stem, the plug is unscrewed and the stuffing box of the shut-off needle is changed. Later, all previously dismantled parts are returned to their places.

Pay attention!
During work, you need to consider that a blowtorch is a source of increased fire hazard. Consequently, during its repair, primary fire extinguishing means must be in close proximity to you.

Household blowtorches are used to heat containers with non-flammable liquids, repair work, soldering and heat treatment. They are systematized by the type of fuel used - gasoline, gas and kerosene. Gas blowtorches or burners are considered the most modern and comfortable to use. But gasoline fans zealously defend their judgment.

Instructions

1. High-tech gas blowtorches combine ergonomic design and high safety in use. They can work independently from disposable gas cylinders and from refillable ones. Punctuatable cylinders without a valve are quite cheap. The body of the lamp itself can be plastic or metal.

2. Universal gas lamps They work on 2 types of cylinders and are connected to them using threads. Such equipment is super compact, which makes it very convenient for storage and transportation. Another advantage of a multifunctional lamp is the likelihood of disconnecting gas cylinder at any moment.

3. Pay attention to the high-tech lamps that operate on the new KEMAP valve cylinders. These aluminum-bodied cylinders contain a special mixture liquefied gases Based on petroleum (LPG), it provides high soldering performance. Previously, this was achieved only by using acetylene. If you are a skilled solderer and welder, a lamp running on these cylinders is your choice.

4. There are gas burners that also operate from domestic propane cylinders. They are very strong, loyal and have versatility when choosing a gas source. For work, use a hose of any length. For roofing works pick up lamp, which is equipped with a long nozzle and a lever for rapidly increasing the flame.

5. For those who like to make new electrical appliances, there are gas micro-soldering irons, and the gas container is located inside them. Before use, it is filled with gas from a lighter can. This is also good idea for a gift to a man with skillful hands.

6. Gasoline blowtorches provide very high heating temperatures - up to 1100 degrees. The strength of its flame can be easily adjusted. Lamps that run on kerosene and second-grade gasoline are used to heat huge soldering irons and to work with hard solders.

7. Both lamps have some pros and cons, but there is a wonderful solution - a multi-fuel universal burner. It runs on any type of fuel from diesel to gas, but such a unit costs about 6-7 thousand rubles.

Energy-saving lamps are designed for lighting not only residential premises, but also social institutions. Their difference from other lamps lies in the content of 5 mg of mercury in the form of vapor, which, if not properly disposed of and processed, poisons the soil and air, which leads to irreversible consequences for human health and environment. Therefore, all users of energy-saving lamps should know the methods of their disposal.

Instructions

1. Take burnt-out energy-saving lamps to the regional DEZ or REU, where containers specially prepared for this must be installed. And from there they are sent to special enterprises, the main activity of which is the processing of energy-saving lamps.

2. If there are a lot of lamps, which is important for offices and enterprises, then it is best to conclude an agreement with a company that is engaged in the reception and subsequent disposal of waste containing mercury.

3. It is advisable to return energy-saving lamps in their original packaging. If it is not preserved, wrap the lamp in paper so that it does not break during transportation.

4. If a lamp breaks, then its fragments cannot be swept away with a broom or collected with a vacuum cleaner, so as not to disperse harmful mercury vapor throughout each apartment. Treat the area where the lamp was broken with a freshly prepared solution of potassium permanganate to bind mercury. After this, thoroughly ventilate the room in order to completely get rid of mercury fumes. Collect the remains of the lamp in a glass container, which will then need to be tightly closed with a lid, and hand it over to a specialized organization.

5. Disposal of energy-saving lamps is carried out in two ways. One of them is washing, grinding and further processing the lamp used with special chemical reagents that combine mercury into a no longer dangerous compound. Another method is thermal. A previously broken lamp is heated, resulting in the evaporation of mercury. Its vapors are condensed and collected in order to be used in the manufacture of new lamps.

Pay attention!
The main thing to remember is that energy-saving lamps cannot be thrown into the garbage chute or container near the house.

Useful advice
Mercury-containing waste, including energy-saving lamps, is disposed of, isolating it from the environment. It is under no circumstances possible to do this on your own.

The UV lamp is prepared for health-improving procedures. Ultraviolet irradiation has right action on processes occurring in the body, and also helps improve the condition of certain diseases.

Instructions

1. The UV lamp is used to increase the body's resistance to infections (flu, ARVI, etc.), for the prevention and treatment of rickets in pregnant and lactating women, and children. It is used to treat pyoderma, pustular diseases of the skin and subcutaneous tissue, improve recovery processes in fractures, normalize immunity in chronic inflammation, stimulate hematopoiesis (the process of hematopoiesis), and compensate for lack of sun.

2. Dosed irradiation with a UV lamp has a positive effect on the body. The procedure regulates blood circulation, accelerates metabolism, increases immune activity, promotes work defense mechanisms during epidemics of viral infections. The UV lamp has a negative effect on the retina of the eyes, so the procedure must be carried out with special glasses. Instead, you can place cotton pads on your eyelids. Some people, due to the characteristics of their body, are not able to tolerate unnatural radiation; therefore, their condition must be monitored during the procedure. UV therapy sessions are not suitable for people who experience dizziness, headaches, nervous irritation, etc. during irradiation.

3. Before the session, moderately treat the skin with cream or oil, apply them in a thin, even layer. Turn on the lamp and wait 5 minutes for it to warm up. Position work surface device at a distance of 10-50 cm from the body surface. If you need to carry out local irradiation of the skin, limit the diseased area from healthy ones using a towel or sheet. For local irradiation (say, the mucous membranes of the nose, throat), before turning on the lamp, install a special tube in the hole in the device screen.

4. The 1st session should last no more than 1 minute, after which you can begin to gradually increase the duration of the procedures up to 5 minutes. In order to prevent ARVI influenza, carry out ultraviolet irradiation of the mucous membranes of the nose and throat for 1 minute on each area. Every 3 days, increase the duration of the session by 1 minute until you reach 3 minutes. The course consists of 10 procedures. During the acute stage of the disease, irradiation is not carried out. Contraindications to the use of a UV lamp are the following ailments: severe kidney damage, heart damage with circulatory failure in the 3rd stage, coronary artery disease, stage II-III hypertension, severe exhaustion, tendency to bleed, anemia, skin diseases, hyperthyroidism. The UV lamp is not designed for tanning.

Useful advice
If the condition of the cuff on the rod is unsatisfactory, then be sure to replace it with a new one.

A vessel with liquid, a rubber bulb, a nozzle... But if you bring a lit match to it, a bright blue flame will flare up, like gas burner. Gasoline is poured into the vessel, it evaporates, and its vapors mixed with air produce a flame with a temperature of about 1100°C. Therefore, the spray burner can melt not only tin, but also hard brass and silver solders. Such devices are widely used by jewelers, dental technicians, watchmakers, fine mechanics and, of course, home craftsmen.
A vessel with a capacity of about 250 cm3 is machined from plexiglass or metal.

The body of the blowtorch is made of brass, the shut-off valve (faucet) is rubbed in with GOI paste. The quality of the grinding is checked by lowering the body with the tap into a vessel with water: plugging the hole for the burner with your finger, pump up the air with a rubber bulb and see if any air bubbles come out from under the tap. The connection between the body and the vessel must also be airtight. A gasket is installed for this purpose.

The burner of the blowtorch is machined from brass and screwed into the body. When drilling holes, be very precise specified dimensions- otherwise the burner will not work satisfactorily.

After assembling the burner, you need to check whether it holds pressure, and only after that add gasoline. (If possible, use gasoline premium grades, for example, aviation, pharmaceutical purified or industrial, known as “galoshes”). After filling the vessel 3/4 full with gasoline, open the tap and pump in air. At the same time, bring a lit match to the burner spout. By adjusting the gas supply with a tap, you can get flames of varying intensity and different temperatures.
When soldering, it is necessary to take into account that it is difficult (and sometimes simply impossible) to heat thick and massive parts to the required temperature with a small gasoline burner. In this case, you should first hold the parts over gas stove or a blowtorch, and perform the soldering itself with a gasoline torch, as described above.

In terms of fire gasoline burner is safe, but as a precaution, it is advisable to have a piece of thick rag or felt at the workplace, which can easily extinguish the flame in the event of any unexpected outbreak.

A gasoline torch for a blowtorch may be inconvenient if you need to perform soldering in any hard to reach place: the vessel is interfering. We suggest making a remote burner on a long rubber hose, which can be used on long distance from a container of gasoline. It is advisable to attach a small handle holder to the burner so as not to burn your fingers during prolonged use.

Repairing blowtorches widely used in everyday life is quite possible on our own. The device is designed for soldering metal parts; it is also used for removing paint coatings from the metal surface. Only a working blowtorch should be used, so the device should always be maintained in working order. If a sudden breakdown occurs, you can quickly repair the lamp yourself and continue working.

Why might a lamp fail?

The device is used for rapid local heating and experiences significant loads that can damage it. To prevent serious damage when using a lamp, you must follow safety rules.

Lamps break due to improper use and overheating.

When the appliance is switched on or has not cooled down, do not fill it with fuel or open the lid of its reservoir. It is also necessary to ensure the tightness of the valves and connections of the pump. Proper operation will allow you to avoid complex repairs or purchasing a new device.

Even if you comply preventive measures failure may still occur. Therefore, it is advisable to always have on hand the minimum set of tools necessary for repairs. You need to know the structure and weak points of the device, which will allow you to quickly and effectively repair the blowtorch. Only after accurately identifying the malfunction and finding out the cause of the breakdown can you begin self-repair tool.

Troubleshooting fuel and air supply problems

To repair a blowtorch you will need a screwdriver, pliers, and thin wire.

If fuel does not flow correctly when the valve is opened, for example, it foams or leaks through the base of the nozzle, the jet may be clogged. Then you should repair the blowtorch using the following tools:

• needle or thin wire;
• straight screwdriver;
• pliers.

Materials:

• petrol.

Repairs are carried out by performing the following steps:

1. If there is a slight blockage, use a needle to clean the calibration hole of the fuel tube.
2. If there is no result, the nozzle is dismantled.
3. Then the wire is inserted into the hole in the fuel pipe.
4. Then open the valve and thoroughly and carefully flush the channel with gasoline.
5. Assemble the lamp by mounting and fixing the jet.
6. If a flame appears from under the stem, the fire should be extinguished immediately.
7. Then the valve handle with the plug is removed and the stuffing box in the intake needle is replaced.

The lamp's air pressure level inside the chamber may be disrupted. In order to repair the device, remove carbon deposits from the channels used for air supply by washing them with trichlorethylene. Then it is advisable to wash all holes with acid and blow with compressed air to remove rust. After this procedure, the device for a long time will not require repair.
